Do These Pennies And A Dime Have Errors?

Both a broadstrike error and an off centered error are struck without the collar die. The collar die forms the edge of the coin so on your dime in order to be a broadstrike it will not have reeding on the edge. Your one cent coins appear to be slightly misaligned dies like profiler said. They don't have a premium until the design goes off the coin. But you can have slight misalignment on both sides so this isn't conclusive to an off centered strike. Since an off centered strike is struck out of the collar, for coins with a reeded edge there will not be reeding around the circumference of the coin and on unreeded coins I would first check the diameter expecting it to be oversize.
